【摘要】：针对可重构机床模块配置设计方案优选排序问题,提出基于集对分析的改进多目标综合决策评价方法.通过工艺需求的转化,根据功能到结构的映射关系,求解出一系列机床模块.通过模块配置准则,实现可重构机床的模块配置设计方案.采用集对分析理论对可重构机床模块配置设计方案评价因素的不确定性和模糊性展开分析,对评价因素构建模糊语言值.将模糊语言值转化处理为三角模糊数,建立评价决策矩阵.结合层次分析法(AHP)确定指标权重以提高方案优选的可信性,引入方案贴近度对备选方案进行排序,建立综合评估决策模型,以实现对可重构机床模块配置设计方案的优选,求解得出最优的配置设计方案.选取某可重构机床的模块配置设计方案实例说明该方法的应用及可行性.
[Abstract]:An improved multi-objective comprehensive decision evaluation method based on set pair analysis is proposed to solve the problem of optimal selection and ranking of reconfigurable machine tool module configuration design scheme. According to the mapping relation between function and structure, a series of machine tool modules are solved through the transformation of process requirements. The module configuration design scheme of reconfigurable machine tool is realized by module configuration criterion. The uncertainty and fuzziness of evaluation factors of reconfigurable machine tool module configuration design scheme are analyzed by set pair analysis theory, and the fuzzy language value of evaluation factors is constructed. The fuzzy language value is transformed into triangular fuzzy number and the evaluation decision matrix is established. Combined with Analytic hierarchy process (AHP) to determine the index weight to improve the credibility of the optimal selection, the scheme closeness degree is introduced to sort the alternatives, and a comprehensive evaluation decision model is established to achieve the optimal selection of the reconfigurable machine tool module configuration design scheme. The optimal configuration design scheme is obtained by solving the problem. The application and feasibility of this method are illustrated by an example of module configuration design of a reconfigurable machine tool.
